Daenerys in Winterfell would disrupt the existing power dynamics in multiple ways. For one, her very presence as a Targaryen with a claim to the throne challenges the Stark's authority in the North. Her dragons are a huge factor; they could be used to intimidate or be seen as a great asset. This might lead to some characters trying to manipulate her for their own gain. For example, Littlefinger (if he were still alive) might try to play both sides, using Daenerys against the Starks or vice versa. Also, the common people in Winterfell would be divided in their opinions of her, some seeing her as a savior and others as a foreign invader.
Perhaps Daenerys comes to Winterfell seeking refuge from the approaching White Walkers. The people of Winterfell are initially hesitant to welcome her, but as they see her determination to fight the common enemy, they start to accept her. Daenerys then discovers some ancient secrets in Winterfell's crypts that could potentially help in the battle against the undead. Her dragons also start to interact with the magical elements in the North in strange and unexpected ways.
A professional army in a Game of Thrones fanfiction would change power dynamics in many ways. Firstly, their presence might make certain regions more stable if they are under the control of a just leader. However, it could also create more tension. Other kingdoms or factions might see this as a threat and start to build up their own forces or form coalitions against the one with the professional army. It could also influence the politics at court, as diplomats would have to consider this new military strength when making deals or treaties.
He would change the power balance. His raw strength and speed could intimidate some opponents. And his strategic thinking would make him a tough opponent to plan against.
He would add more chaos. Since he's a powerful and unpredictable character, his actions would disrupt the normal flow of the tournament. He might target strong fighters first to gain an advantage.
Harry's magic would be a game - changer. His ability to apparate could make travel and espionage much easier. For example, he could easily get into the Red Keep undetected. This would give him an edge over the regular characters in GoT who rely on horses and ships.
Bardock's presence would likely add a new level of intensity. His Saiyan warrior spirit would inspire the other Universe 7 members. He might be more aggressive in his fighting style compared to some of the others, which could either lead to quick victories or put him in risky situations.
In many 'Game of Thrones' fanfics, different characters could be considered the 'real' lady of Winterfell. It could be Sansa Stark, as she has a strong claim to Winterfell through her Stark heritage. She has endured a great deal and learned the ways of politics, which would make her a worthy lady of the keep.
Well, if we consider modern tech in Westeros in a fanfic, guns would completely change the way battles are fought. Armies that get hold of gunpowder technology first would have a huge advantage. For example, the Lannisters with their wealth could potentially mass - produce guns and gain even more power. Also, communication technology like radios would make it easier for lords to control their lands and respond to threats quickly.
